T0 LZZ whom t may concern;

Be it known that I, MICHAEL MARY BRO- PHY, a subject of the Queen of Great Britain, residing at 251 High Holbox-n, London, England, have invented new and useful Improvements in Radiators for Warming Buildings, of which the following is a specification.

My invention relates to heat-radiators for warming buildings and to that class` of such radiators provided with hinged leaves or sections .for permitting of the thorough cleansing of the same at all parts, the object of my present invention being to simplify the construction of such radiators and reduce their cost.

In the accompanying drawings, Figure 1 is a side elevation of a radiator constructed according to my present invention. Fig.'2 is a plan view of the same. Fig. 3 is a horizontal section through one of the leaf-sections. Fig. 4 is a vertical section of the footpiece upon which the hinged leaf ofthe radiator tu rns,and Fig. 5 is a horizontal section taken through the lower part of the radiator-leaf` above the footpiece. Fig. 6 is a vertical section of a bearing-wheel for supporting the free end of the leaf.

a is the leaf of a radiator, which, as shown.

in Fig. 1, is composed of two parts or sections b b, each of which is in the form of a hollow plate having hollow vertical tubular portions c c at the ends, as shown clearly in Fig. 3. It is `to be understood, however, that a leaf may be composed of a single plate b or of more than two of such plates. These plates b b, which are placed one upon another, so that their vertical tubular portions are in alinement, are preferably connected together by nipples, such as d, (indicated in dotted lines in Fig. 1,) having right and left hand screwthreads, in a well-known manner, the said nipples having internal lugs or ribs to permit of the engagement of a tommy or wrench therewith.

The leaf d is supported at its pivotal end upon a hollow foot e, Figs. l and 4, to which the iiow and return pipesfg of the circulating system are attached, the aperture in the foot to which the flow-pipefis connected having in connection with it inside the foot an elbow t', into the open end of which an extension-pipe] can be inserted to pass up through the vertical tubular port-ion c to nearly the top of the leaf, whereby the hot water which enters through the pipef passes to the top of the leaf and after iiowing through the sec tions gravitates down through the space k in the foot to the return-pipe g.

The connection between the footpiece e and the lower end of the adjacent socket c is effected through the medium of a connectorring Z, screwed or otherwise fixed to the adjacent end of the said vertical tubular portion c and provided with a flange Z, designed t0 rotate upon a bearing-surface Z2 in the foot, the said ring being held in position in the foot by means of a kind of gland m, adapted internally to fit the exterior of the connectorring Z and externally to screw into the upper end of the foot e. The flange Z of the connector-ring is formed with a groove on the under side to receive a packing-ring n, and

.the bearing-surface Z2, upon which the said packing-ring rests, is in the form of a rib, which projects into the said groove to form a tight joint to prevent leakage. Between the gland and the upper side of the said iiange Z I preferably insert a corrugated washer 0, of spring-steel, which tends to keep the packingring n in close contact with the bearing-surface Z2, notwithstanding any wear which may take place between the said ring and this surface.

At the lower end of the lowermost tubular portion c is a bearing wheel or roller p, Figs. l and 6, capable of rising and falling relatively with theleaf in order to pass over inequalities in the floor.

In order that the same amount of support shall practically be afforded to the leaf o. at all times, notwithstanding the up-and-down movement of the bearing-wheel p, and no additional strain put upon the hinged point of the said leaf when the said wheel is passing over, say, a projection on the door, as would be the case if the wheel were simply acted upon bya spiral spring, I provide the following arrangement: The bearing Wheel p is mounted in bearings in a box p', capable of sliding in an outer box 192, which is [ixed in the lower end of a tubular portion c, a screw or other pin p3 being inserted through the outer box p2 and projecting into a slot p4 in the inner box p' in order to hold the said inner box within the outer box and at the same time permit of its vertical movement therein. Within the inner box p is placed a spiral spring q, the lower end of which rests upon IOO an annular shoulder q/ and the upper end -of which carries a bearing-plate q2, upon which are pivoted two levers r rr, each of which levers is connected at one end by a link r' to a bridge-piece r2, mounted upon the spindle of the roller p and passing over the latter, While their other ends are in contact withfa rib ori flange s on the inside of the box p2.

It will be understood that the spring q is normally under a certain amount of compresi sion suitable to the weight to be supported, the weight being actually carried by the levers r r and transmitted through them and the bearing-plate q2 to the spring q. The position ofthe point where each link i" and lever 1 r are connected and of the fnlcrum of suclp lever relatively with one another is such that; when the leaf a is moved and, say, the wheel; or roller p enters a depression in the Hoor, so` that the spring q expands, each lever r willi be moved into a more nearly horizontal posi tion, thereby increasing the distance of thei line of draft of its link r from the point ofi pivoting of said lever r, and thus increasing; the leverage of the spring upon said leveinl The weakening of the expanded spring will, therefore be compensated for by the increase; in leverage, and the upward stress exertedl by the outer ends of levers r upon'the shoul-i der s will remain constant. On the other hand, if the roller or Wheel p rises overa projection upon the floor each of the levers r r will assume positions more nearly vertical, and the distance between the line of draft off? its link r and the point of pivoting will be. decreased, and thus decreasing the leverage of the spring. The decreasingr of the lever-s age ot' the spring will compensate for the in-f creased tension of the compressed spring, and the upward pressure of the outer ends of thei levers r upon the shoulder'will therefore re-` main constant. It will thus be seen that the` upward pressure of levers r r upon the shoulder s remains constant under all conditions.

Having now particularly described and as-1 certained the nature of my said invention andi in what manner the same is to be performed,5 I declare that what I claim isl. In a heatradiator, the combination with@` a hollow stationary foot provided with an inlet and discharge aperture, of a radiator leafl or section pivotally connected to said foot and y having a hollow vertical portion extending upward from and communicating with said lfoot and a pipe extending from the inlet ofi said foot to a point adjacent to the top of said, vertical portion of the radiator, substantially as described.

2. In a heat-radiator, the combination with a hollow stationary foot provided with an in-` let and discharge aperture and having an aperture in its upper face, a socket to pivotallyy receive a portion of a radiator-section, of al radiator leaf or section pivotally engaging. said socket and provided with a hollow vertical portion in line with said socket and coml`n1unicating with said foot, a pipe extending from the inlet of said foot toa pointadjaccnt to the top of the said vertical portion of the radiator and a bearing wheel or roller for supporting the outer end of the radiator, substantially as described.

3. In a heat-radiator, the combination with a `hollow stationary foot provided with an inlet and discharge apert-ure and having an aperture in its upper face, a socket to pivotally receive a portion of a radiator-section, of a radiator leaf or section adapted to be pivotally connected to said foot, a connector-ring secured vto said radiator and engaging said socket in the foot, a gland for securingr said ring movably in said socket, substantially as described.

4t. In a heat-radiator, the combination with a hollow stationary foot provided with an inlet and discharge aperture and having an aperture in its upper face, a socket to pivotally receive a portion of a radiator-section, of a radiator leaf or section adapted to be pivotally connected to said foot, a connector-ring secured to said radiator and engaging said socket in the foot, a gland for securing said ring movably in said socket, said radiatorsection having 'a hollow vertical portion in line with said ring and the socket in said foot and a pipe extending from the inlet in said `foot to a point adjacent to the top of the said vertical portion of the radiator, substantially as described.

5. In a heat-radiator having a hinged vleaf or section, the combination 'with a foot upon which the pivotal end of the said leaf is carried,of a bearing-wheel at the free end of the leaf, the weight vbeing supported upon the said bearing-wheel through the intermediary ol a spring and pivoted levers whereby the spring acts uniformly under variations inthe vertical position of the Wheel, substantially as described.
